Thanks MM! I went to the music shop – my cables are faulty, and the melodica is fine!!! ? Phew!
I bought a new cable. The guys told me I should plug straight into the PreSonus box and turn up the signal, before buying a pedal.
One day I’ll get a pedal, because I like the idea now. But I’d like to graduate up to it, so let’s see how far I can get without one. Am relieved and happy. Must record again soon.
